pq and pr are opposite rays. If pq is represented by 4x + 26 and pr is represented by 2x+34, find x

Answer 1

Don't know how you can represent a ray by a number. A ray has no length, as it starts at p and goes on forever.

If you mean pq and pr are equal lengths of opposite rays, then

4x+26 = 2x+34
and
x=4

But there was no need to bring rays into the discussion.
